Sony Xperia Z3 with Office 365…Contacts & Calendar Don’t Sync

If you've recently picked up a new Sony Xperia Z3 (or if you have a Z3 Compact, Z2x or maybe even the much older Zx that have been updated) and your Exchange ActiveSync account is not syncing your Calendar or Contacts to the phone, here is how to make it happen:

If you've already added your Office 365 mail account on your Sony Xperia Z3 using "Exchange ActiveSync" as the type, it should show up as "Mail" - you can go ahead and delete this account

Once deleted, create a new Account, select Exchange ActiveSync and enter your details

Super helpful, thank you!! Though, I'm now getting a message that I am required to update security settings to give device administrator remote control of security features… not sure I like the idea that my phone can be shut down any time. Can you advise if I have to activate? Thanks in advance.

That is a standard device "policy" warning for the feature of being able to lock/wipe your device from the webmail interface, or if your O365 is with a company, for them to either do that…or do even more (depending on how much/little they want to control your device…such as a full wipe). If it's just a personal O365, just hit OK and nothing will happen.
